Chapter 9Lesson 1How are Organisms Adapted to Survive?Plant and Animal AdaptationsPlants and animals must adapt to their environment. Adaptations help them get food, hide from predators, and survive.

Different plants and animals live in different environments. The place where a plant or animal lives is called its habitat. The habitat of a dolphin is the ocean. The habitat of a cactus is the desert.

Plants and animals have adaptations. An adaptation can be a physical feature, like their coloring or a body part. It might also be a behavior. Any physical feature or behavior that helps a plant or animal survive is an adaptation. The webbed feet of a duck are an adaption that is a physical feature (body part). Hunting at night is an adaptation that is a behavior.Adaptations to HabitatForest - The aye aye sleeps during the day and hunts at night. It has large eyes that help it see at night.CamouflageSome animals hide by looking like what is around them. These animals have an adaptation call camouflage. Camouflage is the coloring or marking of an animal that helps it look like what is around them.Color and MimicrySome animals have bright colors. Other animals can see them easily. This adaptation is called warning coloration. The blue poison dart frog stands out. Its bright color warns predators that it is poisonous.BehaviorBehavior can help a predator as it hunts. Wolves and other animals hunt in groups. The group surrounds the prey so it cannot escape.

Behavior also helps prey survive. Rabbits run in a zig-zag pattern. This behavior can help them escape from predators.Behavior Continued...I Wonder...Hibernation helps animals survive a cold winter by letting them sleep during cold temperatures. What similar behavior might help an animal avoid the hotest daytime desert temperatures?

The animal might dig into the ground or sleep during the day and become active only at night.

Write this on the lines on page 204SummaryTo survive, plants and animals must be adapted to their environment. Their adaptation help organisms get food, hide, and generally survive in the environment. How does running in a zig-zag pattern help a rabbit survive?

Running in this pattern helps a rabbit escape predators.Rainforest - Water that stays on leaves can cause disease. Leaves with pointed ends allow water to drip off.The role a plant or animal plays in its environment is called its niche. A niche includes the kind of food a living thing uses. An opossum's niche includes eating berries at night. Many living things can share a habitat. However, each has its own niche.1. What is the difference between an organism's niche and its habitat?

An organism's habitat is the place where it lives. Its niche is the role it plays there.2. Complete the Venn diagram to compare and contrast the adaptations of the wood duck and the aye aye.Both have body parts that are adapted to their environments and that help them survive.Wood Duck

large eyes to help it hunt at nightCamouflage can help both predators and prey. You know that predators are animals that hunt other animals for food. You know that prey are animals that are hunted.Look at the young deer's fur. The color and spots help the deer look like its forest habitat. Predators have a hard time seeing it.An arctic fox is a predator that uses camouflage. Its fur looks like what is around it. Its prey does not see the fox.3. Tell how each of these animals uses camouflage.

a. young deer: Its color and spots help it blend in with its forest habitat.

b. arctic fox: Its fur blends in with is surroundings, making it hard for its prey to see.Circle the correct answer.4. Which adaptation would be MOST useful to an animal that lives in the forest?

A. bright colors that are easily seenB. muted colors that blend in with the forest floorC. ability to run fast in open areasD. thick fur

Some animals protect themselves by using mimicry. Mimicry is an adaptation where an animal looks like another animal or a plant. Many insects use mimicry. The South American owl butterfly has large spots on its wings. The spots look like the eyes of an owl. These spots scare away birds that might eat the butterfly.5. Label the drawing. Identify whether each animal is using mimicry, warning coloration, or camouflage.The kangaroo rat stays in its burrow during the day. This behavior helps it survive the heat of the desert.6. List five behaviors that help animals survive in their environments.

a. wolves hunting in groupsb. rabbits running in a zig-zag patternc. hibernating in winterd. kangaroo rat staying in burrow in daytimee. archer fish shooting water jets to catch insectsSome animals such as bats, frogs, and chipmunks have an adaptation that helps them survive winter. They hibernate, or go into a deep sleep, during which they use very little energy. This behavior helps the animals get through long, cold winters.The archer fish can shoot a jet of water. This behavior helps it knock insects into the water where it can eat them.ProblemSome animals need to hunt to find food.SolutionSurrounding prey as a group like wolvescamouflage like an arctic foxshooting a jet of water to catch an insect like the archer fishProblem and Solution: What are two examples of adaptations that help animals hunt?Wood DuckAye AyeThis Prezi was created using the following:
